Impatiens grandis x campanulata

This is a close look at an awesome new hybrid, Impatiens grandis x campanulata.  This special cross combines the robust growth of Impatiens grandis with the long flowering season of Impatiens campanulata.  It is a choice collector's plant that happens to be easy to grow!  The plant is new to the horticultural world and i don't think it's available elsewhere online.

Impatiens grandis x campanulata

This perennial hybrid shares the unusual growth habit of Impatiens grandis, with its tree-like shape, rigid stems, and oversized leaves.  So far the plant has grown 2 feet tall, and will probably grow larger.  Its leaves are thick and glossy, growing to about 5 inches long.  Unlike Impatiens grandis, which blooms mostly in winter, the hybrid flowers in waves throughout the year, more like Impatiens campanulata.  The orchid-shaped flowers are 1 inches across and appear in prominent clusters at the top of the shoots.  Its white petals are speckled with red, and each flower has a different pattern.  The 2 parent plants don't cross naturally, so they got a little help from science, through in-vitro fertilization.  The end result is an exceptionally handsome plant that would make a great show plant.

It has grown well with daytime temperatures between 55 and 80F (13-27C) and nights between 45 and 65F (8-18C).  It is untested outside that temperature range.  The parent plants are unhappy in consistently hot conditions, especially if nights are warm.  I don't think the hybrid can survive frost.  It does wonderfully indoors in a pot and is very low-maintenance.  It enjoys bright, filtered light.  Protect it from strong sun exposure.  Like most Impatiens, it prefers fertile, well-draining soil that's kept evenly moist.  Over about 40% humidity is best.
